BasicSoundOutputDemo segmentation fault

Allen_Ingling · October 20, 2009, 1:34pm

Hi there,

I tried to run the BasicSoundOutputDemo on my PC running XP SP3, and it crashed Matlab with a segmentation fault. See below for output. Looking through the archives of this group, I tried to find previous messages referring to this type of problem and found this:

http://tech.groups.yahoo.com/group/psychtoolbox/message/7249

Following the discussion, I tried typing the following on the commandline:

PsychPortAudio('Verbosity', 10); % To enable more debug output...
d=PsychPortAudio('GetDevices')

The second statement caused the same crash. Any suggestions on what the problem might be? Could it be a SP3 issue?

thanks!
Mary

>> BasicSoundOutputDemo

Could not find a low-latency enhanced PortAudio driver. If you need
really accurate sound onset timing and latency < 30 msecs, please read
"help InitializePsychSound" carefully and follow the instructions.
Will use our standard driver instead of enhanced driver...
Unknown Windows exception of type=c06d007e was not caught.

Dear Mary,

Did you try following the directions in the error message you pasted
below? The first few lines might be helpful:

Could not find a low-latency enhanced PortAudio driver. If you need
really accurate sound onset timing and latency < 30 msecs, please read
"help InitializePsychSound" carefully and follow the instructions.

Best,

David

No, BasicSoundOutputDemo should have worked without the low-latency driver, and usually it does, at least i'm not aware of crash problems. But then the problem is "solved" by Mary's upgrade to the low-latency plugin and this seems to be an isolated failure case, so I'll not pursue this further unless many other people report trouble.

Btw. the low-latency plugin for MS-Windows by itself will not provide any low-latency or improved timing accuracy, it just gives you the option of getting these if you have a proper ASIO sound card installed.

best,

You have to call InitializePsychSound before calling any PsychPortAudio function on Windows, otherwise bad things may happen.

> Also, a partly related question, and please excuse me for what seems like an obvious question, when I type in the GetDevices command on similar PC we have, it returns the 1x8 struct:

Look into devices(1), devices(2) etc. for the actual content.

If the devices = PsychPortAudio('GetDevices',3) call gives you anything back, you have some ASIO hardware installed, which is as low-latency as it gets. If you don't have the relevant asio plugin from our wiki installed, or no ASIO soundcard, it won't work.

Also, InitializePsychSound will already print out if you have asio support or not.

Thanks, Mario!

Yes, there appears to be no low-latency device.

However, we installed a non-ASIO supported sound card we had (Creative Labs CT-4750) and ran PsychPortAudioTimingTest on it with the photo-diode, microphone, and oscilloscope. As luck would have it, apparently the timing is much better than we expected. The sound playback was consistently delayed only one refresh cycle (60Hz setting) after onset of the black-white screen transition.

I was considered accommodating this bias in my MATLAB code but could this value (16ms) be inputted into 'biasSecs' in PsychPortAudio('LatencyBias',pahandle [,biasSecs])?

The issue is that we want to place an ERP marker as close to the sound onset as possible in the following way:

t = PsychPortAudio('Start', pahandle, repetitions, 0, 1);
putvalue(dio,ERPauditory); %************ERP MARKER

If I put the 16ms bias into the LatencyBias, will my ERP marker be as close as possible to the actual sound onset?

Perhaps I can set the 'when' argument in PsychPortAudio('Start'...) to 16ms before the ERP marker.

Thanks for any help!
Andreas
